marks a flexible element having its lower end secured at 11 to the bar 2, the flexible element being extended upwardly and downwardly around the roller 8 in the guide 5 and through the groove 9 in the roller. The flexible element 10 passes downwardly through the groove 9 in the roller 8 of the guide 6 and is connected to a drum 12 carriedby a shaft 100 mounted in bearings 14 on the bar 4, the shaft having a crank 15 and being held against reverse rotation by means of a pawl and ratchet mechanism 16. A casing 17 is secured to the inner edge of the bar 2 and a dog 18 is pivoted in the casing, the dog engaging a rack 19 on the inner edge of the bar 4, under the action of a spring 20. A releasing line 21 is attached to thedog 18 and passes outwardly through an opening 22 in the bar 2. The structures above described are duplicated at the opposite ends of the complete mechanism shown in Fig. 1.

Hangers 23 are ing an open head 24 having side openbolt 3, the upper end of the shank being located between the upper ends of the bars 2. The ends of a track 28 are receivedin the heads 24 of the l1angers23. The track includes end casings 29 each comprising a top 30, an end 31, sides 32 and cross webs 33 uniting the sides, the webs having openings 34. Longitudinal seats 35 are fashioned in the upper edges of the sides32, the end 31 forming'shoulders 101 at the extremities of the seats 35. Angle members 36 are provided, the vertical flanges thereof being received in the seats 35 and abutting against the shoulders 101, the horizontal flanges of the angle members overlapping the top 30 Securing elements 27 unite the vertical flanges of the angle members 36 wit the end casings 29, these securing elements being received in the openings 38 of the hanger 23, so as to connect the track 28 with each hanger. Cross plates 39 extend between the angle members 36 and reinforce the same, the plates having flanges 40 united by securing elements 41 with the vertical flanges of the angle members, the plates having openings 43. Through the openings 43 of the plates 39 and through the openings 34 in the webs 33 of the end casings 29,'is extended a truss rod 42, havotherend of the latch 72 has ing its ends connected with the members 31 of the end casings 29.

The structure hereinbefore described may be used with a hay. fork, but by way of illustration, it has been delineated as employed with a dumping bucket 4P1 including a body d5 and a bottom &6 hinged at &7 to the body. Keepers bottom l6near its free edge, the keepers projecting laterally beyond the side walls of the bucket body 15, Brackets 19 are attached to the sides of the body 15 and include guides 50. Latches 51 slide in the guides 50, and cooperatewith the ends of the keepers 18. The latches 51 carry racks 52 meshing into pinions 53 on a shaft 541 journaled in openings 55 formed in the brackets 19. The shaft 51- has a crank 56 to which is attached afieXible element 57 rove across a sheave 58 journaled on the body 15 of the bucket a l. A fork 59 -is connected to the bucket body 415 and terminates at its upper end in a shank 60 carrying a finger 71 and provided with a beveled hook 61.

The numeral 62 denotes generally a carriage mounted to move along the track 28 and including a pair of X-shaped frames 63 1 connected at their upper ends by cross shafts 6-1 carrying rollers 65 cooperating with the angle members- 36 of the track 28. A sheave 66 is mounted on the lower end of the carriage 62, and across the sheave is extended a haul-back line 67 formed into a loop 102 engaged around a sheave 68 carried by the shank 59 of the fork which supports the bucket eat, the end of the line 67 being secured at 69 to the carriage- 62. 63 of the carriage 62 are connected by a rod 70 on which an angular latch 72 is mounted to swing, one end of the latch having a hook 7 3 coacting withthe hook 61 on the dumping bucket, hay fork or like load carrier. The a lateral olfset 74:. A hanger 75 is attached to one of the crossplates 39 of the track 28' or is otherwise supported thereon. A keeper 77 is pivoted at 76, at one end, to the hanger 75 and includes a nose 78 adapted to coiiperate with the angle of the latch 72, the keeper having a notch 79in its lower edge, near to the pivot fulcrumed at 81, between its ends, on the hanger 75. Downward movement of the dog is limited by a stop 82 on the hanger 75. The dog has a counter weighted end 83 and is provided intermediate its ends with an upstanding finger 8 1 cooperating with the notch 79-. A pawl 85 is pivoted to one side of the dog 80, as shown at 86. The dog 80 has a shoulder 87 with which the inner endof the pawl 85 coperates, the construction being such that the pawl can have a limited vertical movement only, on the pivot 86'. The numeral 88 marks a outhaul line connected with the carriage 62.

418 are secured to the The frames 76. The numeral 80 marks a dog The flexible elements 10 may be manipulated by means of the drums 12 toraise or lower the top bars 2 and the track 28. The dogs 18 ooiiperate with the racks 19 to prevent a downward movement of the bars 2 and the track 28. It is possible to disengage the dogs 18 from the racks 19 and to permit a lowering of the track 28, by pulling on the lines 21, the springs 20 restoring the dogs to engagement with the racks, when the pull on the lines is released.

Note Fig. 9. The weighted end 83 of the dog 80 raises the finger 8 1 and the latter supports the keeper 7: The hook- 73 onthe latch 72 engages the hook 61 on the shank 60 of the bucket support, and thus'the bucket is upheld. The carriage 62' is drawntothe right by the line 88. The offset 7 1 on the latch 72 rides along the pawl 85and swingsthe-left hand end of the dog downwardly until the said end engages the stop 82. The latelr 7 2 is tilted on the rod 7 O and'the hook- 73 is disengaged from the: hook 611; This permitsthe bucket 1 1 to be lowered, when the line 67 is slacked' away.- When the dog 80*is tilted as aforesaidgthefinger Stenters: the notch 79in the keeper77, the keeper swinging downwardly, and the nose 78 engaging the angle: of the latch 72-. Thus,the carriage 62 is held while the load isbeing lowered. When the latch 72 moves to-the right, along with the carriage- 62, the-offset. 7 1 rides across the inner'endof the pawl 85, and can pass beneaththe' pawl 85, when the carriage is moved to the left, the parts be-- ing shown thus arranged Fig; 11,:the pawl having a limited upward swinging IILOVGIIIGIIB on its Pivot 86; Thus, the-hook 78 on the latch 72 isso disposed that it may engage with the hook 61- of' the bucket: hanger, when the latter is'raised; Suppose that thebucket has-been lowered and that the parts are arranged as shown in Fig. 11. When the line-67 drawnupon the fork 59 is raised. The finger 71' coacts with the nose 7 8 and rai sesthie keeper77, thus setting the carriage" 62' free, so that it can be drawn to the left by the line 67. When the keeper 77 is raised as aforesaid, the finger 84 on the dog 803s disengaged from the notch 79. The-finger'ZI- holds-- the keeper 77 elevated" swung, under the action-ofthe weight83, into such a position that the finger S L will supportthe keeper 77 in the position of*Fig. 9, when the carriage 62 and the finger 71 move-to the left. When the carriage 62 moves to the right, the bucket is released and may be lowered, the carriage being held untilfthebucket is raised, and when the bucket is raised, the carriage can move der the action of the line 67.
